Since the green tire means the application of new materials and designs, resulting in rolling resistance and therefore lower fuel consumption, low exhaust emissions radial tire. In cars, the energy is consumed by various obstacles, of which about 20 percent is consumed by fuel tire rolling resistance. Use of green tires can reduce energy consumption in this area, so as to achieve the purpose of fuel.
1. Noun interpretation green tire
Since the green tire means the application of new materials and designs, resulting in rolling resistance and therefore lower fuel consumption, low exhaust emissions radial tire. In cars, the energy is consumed by various obstacles, of which about 20 percent is consumed by fuel tire rolling resistance. Use of green tires can reduce energy consumption in this area, so as to achieve the purpose of fuel.
2. Advantages green tire
green tire having a good elasticity, rolling resistance, low fuel consumption, low heat, abrasion, puncture resistance, load capacity, ride comfort and so on. Compared with conventional tires, it highlights the many advantages of environmental protection, energy conservation, new technology and new materials.
● high environmental
Since the conventional tire carcinogenic added rubber compounding agents, as the tread wear are distributed in the air, a serious pollution of the environment, while the world’s hundreds of millions of tires are discarded each year, they not only occupy a lot of space and are difficult to break down, causing a great threat to the environment, known as the “black pollution.” With the increasing awareness of environmental protection, while continuing efforts to reduce rolling resistance at the same time, have begun to pay attention to the materials used for manufacturing tires do not pollute the environment, and efforts to extend tire mileage to reduce the number of waste tires. After a lot of green car tires, have a tremendous effect on fuel economy and reduce pollution. Green tire will be widely used worldwide to save millions of barrels of oil per year, and significantly reduce CO emissions.
● consumption
Black tire is made of the customary use of standard synthetic and natural rubber, in the car under conditions with elevated temperatures, its structure and properties of the shield material are changed, the wheel rolling resistance while also increasing. Compared with ordinary tire green tire, reducing the weight of the tire, reducing the energy consumption of the composite material (hysteresis loss). Therefore, the green tire and the same size compared with the tire rolling resistance can be reduced 22 percentage -35 percentage, thus reducing vehicle fuel consumption and percentage -8 3 percentage that cars CO emissions declined, other properties such as abrasion , low noise, wet and dry roads etc. to maintain a good level of grip.
● Ultrasafe
By optimizing the green tire carcass design, excellent flexibility of the tread to improve vehicle performance in the smooth pavement grip, to make driving more stable, shorter braking distance, greatly improving driving safety. Studies have shown that green tire friction generated can be reduced by 15 percent car braking distance on wet or icy roads, the winter driving performance of the car increased by 10 percentage -15 percentage. This has to reduce accidents and casualties significant
3. The characteristics of the green tire
In theory, there are ways to reduce vehicle fuel consumption weight reduction, tire rolling resistance is reduced and the use of lean burn engines. In fact, only reduce tire rolling resistance is the most practical way to green tire design, research results show that the tire mold, tire construction and tread design and materials have an impact on tire rolling resistance. Overcome tire rolling resistance Fuel consumption accounted for the total automotive fuel consumption.
14.4 percentage, the rolling resistance of the tread produced from only accounted for 49 percentage rolling resistance of tires, the proportion of the influence of other components are: the percentage of the sidewall 14, the percentage of the carcass 11, the bead 11 percentage, percentage belt layers 8, 7 percentage remaining components. Fuel consumption accounts for about tread direct result of 7.1 percentage. Reducing the rolling resistance of the tread and ensure good wet skid resistance of the tire will be green basic requirement.
green tire technology mainly selected from suitable types of plastic and with agents to improve the tread stock recipe start, supplemented by thinning the carcass, preferablyTire profile design of other means to achieve the purpose of reducing the tire rolling resistance. It is expected that the introduction of design results oriented intervention and polymer molecular computer-aided design technology, will undoubtedly accelerate the green tire development process.
